HOSE-CLAMP.

Specification of We latent.

Patented Aug. 19,1913.

I '0 all whom it may concern.

Be it known that I, Amman L. EACRE'I'I, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Hose-Clamp, of which the following is a specification.

This invention relates to hose clamps, and the object of the invention is to provide a hose clamp'which may be instantly attached or detached without the use of any tools.

A further object is to provide a hose clamp of this character which is of extremely economical manufacture, simple in construction, and'etlective and durable in use.

Referring to the drawings: Fi ure 1 is a plan view of the blank from which oneof the members of the hose clamp is formed. Fig. 2 is a plan view of the blank from which the other member of the hose clamp is formed. Fig. 3 is a side elevation of a hose showing the clamp attached thereto. Fig. 4 is a perspective view of the clamp opened. Fig. 5 is a perspective of the clamp closed. Fig. 6 is a section on line wv, Fig. 3. Fig. 7 is a view similar to Fig.6 showing the clamp loosened.

The clamp comprises two members 1 and 2 which are hinged together at 3, each of the members being substantially semicircular and adapted to encircle the hose. Pivot/ed to the member 2 is a lever 4 having a air of teeth 5 which are ada ted to engage in slots 6 formed in the mem r 1. The slots 6 are formed in two sets, as clearly shown in Fig. 1 and staggered so as to give a close adjustment of the clamp.

To apply the clamp it is placed over the hose, the two members swun together as shown in Fig. 7, and then t e lever 4 is swung around to engage its teeth- 5 w1th two of the slots 6 and the lever is ressed down into the position shown in Figs. 5 and 6. If it is found that the two slots with which the teeth 5 are first enga ed give either too loose or too tight a fit of t e clamp, the lever 4 is swung back to disengage the teeth 5 and the teeth 5 are en aged with another set of slots in one directlon or the other according to whether the clamp is too tight or too loose. The staggered arrangement of the teeth permits of a very close clamping adjustment and the desired clam m ressure is easilv secured. In order t0 01 t e lever formed with two wings 8 punched with holes 9, the wings being formed up to receive the lever 4 between them and the pin 10 passes through the holes 9 and pivots the lever 4 in position. The member 2 is widened where the wings 8 join and the base portions of the wings 8 are bent inwardly at 8 toward each other, and then the wings 8 extend outwardly parallel with each other, thereby forming a socket which is adapted to receive the slotted end of the member 1 and positively hold the member 1 from lateral displacement. This slot is somewhat wider than the slotted end of the member 1 to permit of the. necessary lateral movement of member 1 necessary to permit the teeth 5 to be engaged with either set of slots 6. The slot also holds the member 1 from springing outwardly and thus coacts with the teeth 5 of lever 4 to firmly lock the member 1 in closed position. The lugs 3 of the member 1 are engaged in holes 11 which are punched in cars 12 formed on the end of the member 2 as shown in Fig. 2.

What I claim is:

1. A hose clamp, comprisin two members formed of sheet metal, one 0 said members having a pair of lugs at one end and slots at the other end, the other member having at one end a pair of perforated ears an having at the other end a pair of-perforated wings, said perforated wings being bent inwardly toward each other to form a socket, and then bent outwardly parallel with each other, a pivot extending through the perforated ortion of said wings, a lever mounted between said wings on said pivot, said lever having teeth adapted to engage 1n 'said slots, the socket formed between said wings slidably receiving the end of the first member, and permitting a limited lateral movement thereof.

2. A hose clamp comprisin two members formed of sheet metal, one 0 said members having a pair of lugs at one end and having a plurality of sets of slots at the other end, the other member havin a pair of ears with perforations, the ears eing bent at right angles to said member and receiving the lugs of the other member, the second member also having wings bent to form a 'pivot support, said wings being bent toward each other to form a socket and then bent outwardly arallel with each other, a pivot exten ing through said wings, a lever mounted on said pivot, said lever having teeth adapted to engage in said slots, said lever completel filling the space between said wings, and eing thereby held firmly against lateral movement, the first member, having a book 5 In testimony whereof, I have hereunto set 20 my hand at Los'Angeles, California, this 26th day of March, 1913.
